A study was made of the use of 6 wt.% Ru-U all - and - coincidence for the absolute measurement of activities. The principles of the method of coincidences were briefly considered, and the apparatus used was described in detail. The absolute calibration of the radioisotopes Na/sup 22/, Co/sup 60/, Sc/sup 46/, Na/sup 24/, Cu/sup 64/, Au/sup 198/, and Cs/sup 137/ was investi gated. The angular correlations between the radiations were studied, and the results are in good agreement with theory and with previous results. The results were also verified by several control methods using the 4 The effects of counter, liquid counters, and ionization chambers. By the use of two condenser chambers filled with air or argon, the Ra equivalent milligram of several radioisotopes was determined. The results are tabulated. (J.S.R.)
